W10-64 Clevo P150HM gtx670mx
preamble: say you use your laptop for an installation with an external monitor/projector, and want to be able to close your lid keeping the patch open or whatever there is on your laptop display, keeping the fullscreen on external.
Now what W10 and any kind of W as far as I remember is deactivating the display. This is something hardware related I fear, you close the lid, the display goes off. Further with dx11 and its meta-fullscreen, the main display is pushed onto the secondary display showing the bar, plus it messes with the display configuration.
Any idea, can this be fixed in software?
